If 18.1 mLmL of 0.800 M HClM HCl solution are needed to neutralize 5.00 mLmL of a household ammonia solution, what is the molar
AnnyKZ [126]

Answer:

Concentration of ammonia = 3M

Explanation:

The reaction for the question is a neutralization reaction between HCl and NH₃

The chemical equation for the reaction is given as

HCl + NH₃ → NH₄CL

1       :     1          1

Volume of HCl = 18.1ml = 0.0181L

Volume of NH₃ = 5ml= 0.005L

Molar concentration of HCl=0.8M

Molar Concentration of NH₃ =?

Number of moles(n)= Molar concentration × Volume

n = C × V

n of HCL= 0.8 × 0.0181

n = 0.01448moles

Since mole ration for the reaction from the balanced equation above is 1:1,

n of NH₃ = 0.01448

molar concentration (C) of NH₃ = n/v

C of NH₃ = 0.01448/0.005

C of NH₃=2.896

C OF NH₃ =3M

Determine the number of atoms in a 48.3-g sample of zinc. express your answer in zinc atoms using scientific notation.
Paladinen [302]
To answer this question, you need to know the molecular weight of zinc so you can determine how many mol zinc you have. Zinc molecular weight is 65.38gram/mol. Then the calculation would be: 48.3gram/(<span>65.38gram/mol)= 0.74 mol

Since you are asked the amount of atom, you need to multiply the unit in mole with Avogadro number. The calculation should be: 0.74 * 6.02 * 10^23= 4.45* 10^23 molecules</span>
